Benefits of E-Bike Conversion Kits

  • Added biking power. The motors on e-bike conversion kits range in power from as low as 250 to wattage in the thousands. It takes some of the strain off of your legs, helping you pedal uphill with increased ease. A human biking can sustain about 0.35 horsepower units when biking. Even the lowest-powered models can add the equivalent 0.34 units to the equation, effectively doubling your efficiency. 
  • Reach impressive speeds. Especially if you commute via bicycle, then the added speed the conversion kit offers is truly desirable. Able to go up to 20 miles per hour, for class one and two bikes, you can shorten your travels significantly (and not be worn out at the end of your ride). 
  • Eco- and health-friendly choice. Yes, driving a car gets you from point A to point B quickly. But it doesn’t exactly add exercise to your day. Converting your bike to incorporate a motor lets you balance working out with ease of use. Plus, even though it’s powered, it’s still a step forward for the environment. 
  • Easier time climbing hills. Hills are the scourge of bikers, especially in an urban setting. Unlike mountain climbing, it’s challenging to get the momentum needed to make ascending less work. An e-bike conversion kit can help you weather hills on par with San Francisco without breaking a sweat. 
  • Retrofits your existing bike. It takes time to get familiar with the handling of a bike, and many dedicated riders prefer to stick to the tried and true. An e-bike conversion kit lets you hold onto your existing bike while still adding value to its performance. 
  • Much less expensive. All it takes is a passing glance at the price of premade e-bikes to send most running towards an e-bike conversion kit. They are drastically more affordable than getting a new ride; and, though they add weight, the power of the motor usually makes up the difference.
  • Safe on the road. E-bike conversion kits are about more than gaining momentum and riding without encumbrance. They incorporate safeguards, including braking override and well-calibrated throttles. Paired with responsible use, these e-bike conversion kits can help keep you road-ready and safe.

E-Bike Conversion Kit Pricing

  • $100 to $200: You can get some reasonably-powered motors and all the hardware needed to equip your bike with selections in this price range. Generally, these will only include the conversion kit tech—not the wheel or tire.
  • $200 to $500: If your kit is going to come with the wheel, not just the electric components, then expect the price tag to fall in this category. Most have quality motors and come with everything you need for setup. It’s particularly important to check compatibility at this price point since the wheel is typically included. 
  • $500 and up: There are many impressive conversion kits in this price range, complete with the best tech and powerful motors. However, if you end up finding a conversion kit with a high price tag, consider whether it would be better to opt for a pre-made e-bike. 

Key Features

Motor Type

The most essential part of any e-bike conversion kit is its motor. You can find both brushed and brushless motors. The latter enables higher power, though it tends to be more expensive. Brushed motors also create more noise than their brushless counterparts. It also contributes to energy efficiency, which, since these systems run on batteries, is a really important consideration. Brushless motors, however, are preferable since they are less prone to wear and tear and tend to pack more of a punch. 

Power

In order to get the benefits of your e-bike, it needs to have sufficient power to get the job done. In most cases, 250 watts won’t be sufficient when dealing with steep inclines. Conversely, 1,000 watts or higher runs the risk of hitting speeds beyond the legal limits. Though the weight of the system counteracts some of that extra power, you must factor in your surroundings when picking the right wattage. More strain on the bike means you need higher wattage. A light commute means you can get by with a low-wattage system. 

Battery 

Though most e-bike conversion kits don’t include batteries, it remains a critical consideration. For starters, the voltage needs to be compatible with the motor, lest you burn out the circuitry before even hitting the road. The battery powers range between 24 and 48 volts, with the amount of voltage being proportionate to the wattage. Consider the power demands and the battery lifespan. Higher power motors drain batteries more quickly, but they move faster. Lower-power motors move more slowly but extend battery life. The tradeoff between battery life and power is an essential feature to consider.

Kit Materials

Unless you’re a wiring savant, you’ll likely want an e-bike conversion kit that comes with instructions and an intuitive layout. Though the wiring is fairly straightforward, it requires a bit of effort and a lot of hardware. Depending on whether the conversion kit includes a wheel, you’ll need different hardware. If it doesn’t come with the wheel, be sure that your set comes with throttle controls, the motor, the wiring setup, a mounting plate, and all the nuts and bolts to get it in place. 

Other Considerations

  • Compatibility. Anytime you retrofit a piece of sports equipment, you have to make sure the new parts fit. E-bike conversion kits are no different. Many of them are universally compatible, whereas other models are designed for specific bikes. Take a moment and check that the kit will work with your existing bike before you move onto other considerations. 
  • Legal Aspects. The definition of e-bikes was adjusted by the Consumer Product Safety Commission in 2002. It specifies the maximum speed a bike can travel relying only on motor power. Keep in mind that individual states can also impact the rules of the road. Be sure you are familiar with the regulations in your area. 
  • Weight and Balance. It’s no secret that adding hardware to your bike also adds bulk and weight. The power of the motor compensates for any slowdown, but it still has impact on your bike’s frame in terms of weight distribution. Especially if you are getting a high-powered motor, be sure that your bike’s frame can handle the demand. 
  • Available Warranties. Some conversion kits come with a limited manufacturer’s warranty, but make sure to read the fine print. These are almost always exclusive to defects with the product, which usually would be covered under a return policy. The warranty is a failsafe if something arrives in poor condition, but it isn’t insurance against damage from wear and tear (where most damage occurs). Take warranty offerings with a grain of salt. 
  • Bike Applications. Think about what kind of terrain you’ll be navigating. Are you planning on hilly mountain excursions or a slow and steady commute to work? Depending on the pressures your bike will encounter, you’ll need a different type of kit. Finding the best-suited e-bike conversion kit will prevent premature wear and tear and make sure you reap the most advantages from your new equipment.

Best E-Bike Conversion Kits Reviews & Recommendations 2021

Best Overall
Yescom Front Wheel E-Bike Conversion Kit

If you’re looking for a way to embrace the full throttle of electronic bike technology, the Yescom Front Wheel E-Bike Conversion Kit is a powerful choice. This kit comes with a 48-volt, 1,000-watt motor with a maximum of 470 RPMs. Set up to be free of any chains or gears, the low friction coefficient is both energy efficient and reduces wear and tear. Though the entire set is fairly heavy, the weight ends up distributed well across the whole bike. Designed for use on a 26-inch tire, the broad design of the tire lets you remain stable when moving at high velocities. Requiring a front drop-out spacing of 3 15/16-inches, this set works with most bikes on the market. The well-balanced, high-performance features make it an energy efficient model that gets you where you’re going quickly. 


This unit comes equipped with a bright LCD display that shows you speed, time, mileage, battery power, and current gear. It also features a pedal assistance system that lets you still cycle while riding the bike under power. The biggest downside to this conversion kit is that you need to purchase the battery and charger separately, which will significantly add to the overall cost of the unit.

Best Value
L-Faster Electric Bike Conversion Kit

Coming as the electrical supplies alone, the L-Faster Electric Bike Conversion Kit lets you stick to a reasonable budget while enhancing your bike significantly. The chain drive is made specifically for a bicycle with electric gears. The 24-volt electric wheel uses brush motor technology featuring a freewheel structure. It runs on 250 watts; which, while not the most powerful, is a safe amount of power to retrofit a standard bike without causing excess wear and tear or balance issues. Complete with the chain, sprockets, mounting plate, hardware, and thumb throttle, it’s a fairly basic setup, but it gets the job done. The parts are high-functioning and don’t place excessive stress on your bike. Plus, with the low wattage, your battery will last far longer than higher power motors. 


It’s worth noting that this model doesn’t work with bikes that rely on a coaster brake system. The setup doesn’t include a battery or charger either, but for the quality of the hardware included, it’s worth the price.

Best Premium
EBikeling Waterproof Ebike Conversion Kit

The EBikeling Waterproof Ebike Conversion Kit is a rugged, yet lightweight and easy to install kit that will allow you to quickly convert your regular bicycle into an efficient and powerful electric bike. This front wheel conversion kit features an aluminum double-walled rim with the hub motor already attached. It comes ready to install right out of the box.


With this kit, you have the option of choosing between a thumb throttle or a half-twist throttle. As well, you can upgrade from the standard display to a bright and intuitive LCD display that shows you battery percentage, trip distance, wattage, speed, PAS levels, and error codes for advanced troubleshooting.


This kit includes the wheel hub motor, display, throttle, controller, brake levers, pedal-assist system, torque arm, and cable ties. Unfortunately, it doesn’t include a battery or a new tire. You’ll need to purchase those separately or use your existing bike tire. This kit is pricier than many others on our list, but the components are top notch.

Honorable Mention
AW 26

Boasting an impressive 1000-watt motor, the Fdit Electric Bicycle E-Bike Motor Conversion Kit is a great balance between power and price. It’s compatible with any 26-inch bicycle wheel, and since this size is common for urban bikes, the odds it will fit are in your favor. This front hub wheel assembly is capable of reaching speeds up to 45 km/h. The dual mode controller allows the motor to work under Hall and non-Hall effect to help extend the life of the components. The handy and smart pedal assist sensor actually senses your pedal cadence and will adjust the motor turning rate accordingly. This allows you to get power without using the throttle. The aluminum alloy frame is both durable and lightweight.


It does, however, have some drawbacks, particularly in terms of the reliability of some of the system’s components, especially the pedal assist. Customer service response time is also questionable.

Honorable Mention
Ricetoo Electric Bicycle Kit

The Ricetoo Electric Bicycle Kit comes in a variety of different sizes and with different motors, allowing you to get the perfect conversion kit to suit your needs. It’s a lightweight and streamlined kit that’s far less bulky and distracting than many others on the market. Choose from a 36-volt or a 48-volt, 5000-watt brushless motor system. It is able to fit on bikes with tires ranging in size from 16-28 inches. It does require a front fork opening of 100mm in order to be compatible, so be sure to check prior to purchase.


As with many others on our list, this kit doesn’t come with a battery included and it must be purchased separately. The included LED display is bright but fairly basic. It lacks some metrics that many other digital kit displays will have.

Honorable Mention
JauoPay 48V 1000W Electric Bicycle Conversion Kit

If you want an easy-to-install, uncomplicated ebike conversion kit, check out the JauoPay 48V 1000W Electric Bicycle Conversion Kit. It’s comparable to several other kits on our list in both quality and price. It comes with a 48-volt, 1,000-watt brushless, gearless front hub motor that lets you reach speeds of up to 45km/h. It does, however, com default restricted to street-legal speeds of 24km/h for your safety.


The dual motor controller works under both Hall and non-Hall effects for extended longevity and efficiency. This kit features an eight-point high pedal assist system that allows you to activate the motor without the use of the throttle.  We also like the sleek and intuitive design.


What we don’t like is the fact that as with most others, this kit doesn’t come with a battery. It also doesn’t come with an LCD or LED display to show you battery power, speed, trip distance, or any other metrics. 

Honorable Mention
EBikelling Fat Tire Direct Drive Electric Bike Conversion Kit

Not all ebike converters are meant for racing. The EBikelling Fat Tire Direct Drive Electric Bike Conversion Kit is specifically designed for your fat tire bike. In fact, it’s one of the few fat tire bike conversion kits on the market right now. With this kit, you can choose from a thumb or twist throttle. You can also choose between an LCD or LED display, giving you options for personal preference. The aluminum double-walled rim comes with the hub motor assembly already attached for quick and easy conversion. All you have to do is just switch out your tire and hook it up.


The pedal assist sensor lets you easily start the bike without using the throttle, cutting down on equipment wear and tear. We also like that this unit comes backed by a one-year warranty, which many conversion kits don’t offer.


The common drawback to this kit is that it doesn’t come with a battery. Thankfully, 48-volt batteries are quite easy to find, unlike some kits which run on a 36-volt system. Batteries for that are few and far between. There are some good options available for this kind of battery, but the tech is less prevalent than 24- or 48-volt counterparts. 
Honorable Mention
Kunray Electric Brushless DC Motor Complete Kit

If you’re looking for a seriously high-powered e-bike conversion kit that won’t limit you in any way, the Kunray Electric Brushless DC Motor Complete Kit is the perfect pick. This DIY e-bike kit will deliver up to 2,000 watts and 4,300 RPMs of power and give you three different speeds to choose from — and you’ll be able to enjoy extreme power thanks to the included brushless high-speed electric motor. Even though it’s strong, the motor is nearly noiseless. The e-bike kit also includes a handlebar twist throttle with an accelerator, wires, and cables, and all of the pieces you need for mounting and installation. Once it’s installed, you’ll be able to reach impressively high speeds of over 50 miles per hour, all on your bike. Just make sure to carefully control your speed so you don’t fly off your bike while riding.


One drawback to this unit is that it’s not as quiet or efficient as some other conversion kits on the market. There’s also some concern about the overall consistency when it comes to the construction of the motor and other components. 

Honorable Mention
Bafang 48V 500W Bicycle Conversion Kit

The Bafang 48V 500W Bicycle Conversion Kit is a balanced option for anyone who’s looking to upgrade their basic everyday bike or mountain bike. It offers a great combination of extra power and pedaling assistance without too much speed. The 48-volt, 500-watt Bafang BBS02B electric motor is designed to fit a standard JIS 68- to 73-millimeter bottom bracket so it’ll fit right onto your bike frame, and it can be used on commuter bikes, road bikes, and mountain bikes. All of the mounting equipment and accessories you’ll need are included in the kit. It comes with brake levers, a color LCD with Bluetooth connectivity for iPhones, waterproof cables, cranks, a thumb throttle, lock nuts, a speed sensor, and more. Like most Bafang e-bike conversion kits though, keep in mind that you’ll have to purchase a compatible 48-volt battery and charger separately.


Unfortunately, this kit is not effective on bikes with a carbon-fiber frame. Because of the heavy-duty function, it won’t balance properly with the lightweight structure of a carbon-fiber setup. Stick to aluminum or titanium structures to avoid any damage. 

Honorable Mention
CSCbike MTB E-Bike Conversion Kit

If you’re looking for an e-bike conversion kit that’s designed just for mountain bikes, you’ll love the CSCbike MTB E-Bike Conversion Kit. It’s built to take lightweight, rugged ride-ready bicycles to electric heights with a rear-wheel kit that includes a wheel replacement. Designed for mountain bikes with 135- to 142-millimeter dropouts and made to fit disc brake systems, this conversion kit includes a whole wheel replacement. You’ll get a 20-inch wheel with a double-wall tire and aluminum alloy rim along with a 36 volt, 250-watt motor. That motor will enable you to reach speeds of 12 to 20 miles per hour. With an LCD and a Pedal Assistance System, you’ll be able to tackle any terrain more easily. And this conversion kit is even backed by a one-year warranty.


It’s worth noting that this protection only extends to manufacturer defects, with several caveats. If any issues are a result of wear and tear (as they are most likely to be), the coverage doesn’t apply. That said, with proper use, this e-bike conversion kit can last for an impressive amount of time. 

Tips

  • Always check to see whether or not a conversion kit comes with a battery; many do not, and you’ll have to purchase one separately.
  • Some e-bike conversion kits are better for rough riding or mountain biking, in particular, so look for specialized options if you have a favorite biking style.
  • A kit’s motor wattage determines how much speed you can achieve. Higher wattage equals more speed, while lower wattage is best for cruising.

FAQs

Q: Are e-bike conversion kits worth it?

A: It depends on what you want out of the e-bike and the conversion kit motor. Yes, an e-bike conversion kit will add some weight, but if it’s properly distributed and the motor has sufficient wattage, the extra power compensates. The bike might be heavier to lift, but it will make hills and long trips more efficient. 

Q: Are e-bike conversion kits legal? 

A: It is perfectly legal to apply an e-bike conversion kit to a street bike, provided the speed rating falls within the legal limit.  In the United States, class one and two vehicles can be assisted to up to 20 miles per hour. A class three model with pedal-assist but no throttle, you can legally get up to 28 miles per hour. 

Q: Is it cheaper to build your own bike?

A: In terms of whole bikes overall, it’s a safer bet to go with a premade model, especially if you’re on a budget. It is, however, cheaper to build up your ride with an e-bike conversion kit rather than purchasing a fully assembled electronic bike. 

Q: How fast does a 1,000-watt electric bike go?

A: You can technically reach speeds of up to 35 miles per hour at max throttle, well beyond the street-legal limit. However, when used on trails, the extra power can lend a big assist when handling hill-heavy trails. Even when it comes to pavement with steep inclines, the max mileage reduces due to the motor’s strain when handling the angle. 

Q: Can I convert the bike I currently have?

A: Just about any bike can be converted into an electric bicycle with an e-bike conversion kit. More complex bikes with intricate gear systems may be a bit trickier to work with, but with a quality kit, any bike can begin running on electric power.

Q: What does it take to install an e-bike kit?

A: Most electric bicycle conversion kits include all the parts and pieces you’ll need for installation. However, you may need to purchase a battery separately to power your new e-bike. You’ll also want to have a variety of tools on hand, like wrenches, pliers, and screwdrivers.

Q: How much does it cost to convert a bike to electric?

A: The cost of e-bike conversion kits varies quite a bit. It depends on a few different factors, like the items that come with the kit, how powerful the motor is, and whether or not a battery is included. Kits can range anywhere from $100 to $1,000.
